CONTAINER AND SEAIING MEANS TI-IEREFOR.

My invention relates to containers which are provided with bungs in the form of threaded plugs which are received within the threaded interiors of bushings that are 5 assembled with wall portions of the containers, the invention finding particular use in connection with barrels in which oil or other liquid is packaged for shipment.

The invention has for its object the proie vision of means for obstructing undetectable access to and removal of the plugs. To this end I employ a sealing device or guard assembled with a container wall and positioned to prevent undetectable access to the plug, which usually has a tool engaging formation upon* its outer end, access tok which is obstructed by the guard.

In the preferred embodiment of the invention, the guard is in the form of a hood 2O which completely covers the otherwise eX- posed outer end portion of the plug so that not only is access to the tool engaging formation of the plug, guarded against but access of other dislodging tools such as chisels and punches is also guarded against.

In the preferred embodiment of the invention, the guard orhood is clamped in a space between the container wall and a -flange that is provided upon the outer end portion of the plug. The bushing is (lesirably also provided with a flange that is located in this space, the guard or hood being clamped between the flanges upon the plug and bushing.

The invention will be v inore fully explained in connection with the. accompanying drawing in which Fig. 1 is a view 1llustrating the preferred embodiment of the invention, the bushing and a portion of the container wall being shown in section while the plug and the guarding or sealing device that protects its outer end are shown in elevation; Fig. 2 is a plan view of the structure Shown in Fig. 1; Fig. 3 is a sectional view on line 3-8 of Fig. 1; and Fig. 4 is a view on a larger scale of a portion of the structure, partly shown in elevation and partly in section.

The container, such as a barrel, has one wall 1 thereof formed with a depending `rim 2 which surrounds a circular hole formed through this wall. An interiorly threaded bushing 3 is snugly received within this hole and is closely surrounded by saidY rire, this bushing being shown with an Application led March 3, 1927. Serial No. 172,375.

outwardly curled inner edge portion 4; which grips the inner edge of said rim 2 and a circumscribing flange 5 which is tightly seated upon the wall 1, this flange desirably lapping this wall on the exterior of the container. The closure plug 6 is screwed within the bushing 3 and is formed with a circumscribing flange 7 which laps the Harige this recess being of square or other contour i to receive a wrench having a plug formation snugly receivable within and corresponding` in shape to said recess.

The sealing device or guard of my invention is preferably in the form of a hood comprising a body or skirt portion 11 which has a part that is inwardly turned at its inner end and confined between .the gasket 8 and the bushing flange 5, this hood body -or skirt being preferably firmly clamped in position when the screw plug is driven home, the portion of the body between the flanges upon the plug and bushing being tightly clamped between these two flanges. Said hood also includes a cap portion 12 which `is not initially assembled or fully assembled with the body or skirt portion 1l, the closure plug being tightly applied before the cap is finally assembled to enclose the plug portions 7, 9. The outer annular edge of the skirt portion 11 of the guard or seal may be initially hook shaped in cross section, as indicated at 11 at Fig. Ll, The cap portion 12 may be provided with an annular hook portion 12f that is enmeshed with the hook portion l1 after t-he plug 6 has been firmly seated, a suitable tool being employed for so thoroughly incorporating the hook portions 11, and 12', together that the cap portion 12 can not be removed without the removal being detectable. f I

All of the plug upon the exterior of the container is thoroughly guarded from undetectable aceess by the construction described. 'Ihe bushing 3 and its flange 5 surround tbe pertion of the plug that is in their li t) zone. The sealing member, ll, 12, protects all of the plug in the outer zone adaient theflange o. The material of which the hootlis made is desir-ably very thin sheet metali surhastin which will readily tear or become ruptured. if any attempt is made to loosen the plug as by mainsV of wrenches applied to the plug ilangep' or the plug enlargement 9.

lhe cap portion ll of the hood may have a circuinscribing ledge 122 between its body portion and its hook portion This ledge may be formed with identifying -111- dcntations 12"' which receive corresponding formations upon the outer annular edge of the body portion ll. of the hood.

Preventing undetectable access is referred to in the claims in the sense that access vassembled with said container wall by said flange and covering the outer end of said plug to prevent undetectable access thereto.

2; The combination with a container formed with a hole through a wall thereof; of an interiorly threaded bushing assembled with said wall in alignment with said hole, said bushing having a circumscribing .flange which laps the wall where the wall surroilnds said hole; a closure plug screwed within the bore of the bushing and having a tool engaging formation upon its outer end; and a hood comprising a body portion assembled with said container wall by said llange, and a cap portion joined with said body portion and covering said tool engaging formation to prevent undetectable access thereto.

3. The combination with a container formed with a hole through a wall theleof; of an interiorly threadeil bushing assembled withsaid wall in alignnientwith said hole, said bushing having a circuinscribing flange which laps the wall where the wall surrounds said hole; a closure plug screwed within the bore of the bushing; and a guard comprising va body portion assembled with said container wall by said flange, and a portion joined with said body portion and covering the outer end of said plug to pre vent undetectable access thereto.

4.
